Abstract

Method provided by the present invention is with magnesium chloride solution, light magnesium oxide; lightweight or hard aggregate such as wood sawdust, sand, microlith; fiber reinforced material such as glass fibre and other subsidiary material are by certain proportioning; through the mould → vibration → curing → demoulding → maintenance of selecting materials → prepare burden → stir → go into → be coated with the production technique that adds protective layer, in various different moulds, make the method for multiple product.As products such as well lid, cage, prefabricated wall cabinet, imitation sculpture, firm prefabricated house, sanitary ware, tubing, deck panels, non-bearing wallboard, sash.Have cost low, economize on resources, indeformable, glossiness good, the mechanical index advantages of higher.

Description

The manufacture method of fabric enhanced magnesite products

The invention provides a kind of manufacture method of fabric enhanced magnesite products, belong to technical field of buildings.

At present, magnesite product is mainly used in ground and finishing material etc., the folding strength deficiency, and some product is crossed shortcomings such as for a long time yielding.

The purpose of this invention is to provide a kind of intensity with fabric enhanced magnesite products; and admixture lightweight or hard aggregate and other add auxiliary material, through the mould → vibration → curing → demoulding → maintenance of selecting materials → prepare burden → stir → go into → the be coated with method that the technology that adds protective layer is made various goods.

The object of the present invention is achieved like this, with a certain proportion of light magnesium oxide (MgO), magnesium chloride (MgCl ₂6H ₂O) solution; fiber reinforced material such as glass fibre, aglite such as wood sawdust; hard aggregate such as sand, microlith; also can add stirrings such as mineral color and other auxiliary materials such as fire retardant, water-resisting agent, defoamer; manufacture a product by above-mentioned technology; can there be skeleton inside, and the outside can be coated with and add protective layer.

The prescription of main raw of the present invention (by weight): magnesium chloride solution (ripple magnesium density 28-34 degree), light magnesium oxide, wood sawdust, glass fibre are 6.5-8: 10-13: 0.8-1.2: 0.3-1 and other an amount of auxiliary materials.

The test block of method of the present invention has good mechanical index, and ultimate compression strength can reach 35-60MPa, and folding strength can reach 10-16MPa, No. 25 no changes of freezing and thawing test, acid and alkali-resistance.Can make the product of different shape, size, floral designs with different moulds, lift several examples below and further set forth.

Example 1, can make the well lid, cage (in skeleton is arranged) of public works such as plumbing with present method, can reach national design requirements, and cost is low, anti-lost, economize on resources, and overcomes the crisp shortcoming of cast iron and hydraulicity (declare utility model application number 92228572.1).

Example 2, make the prefabricated wall cabinet with present method, more attractive in appearance, exquisite than cement products, need not add skeleton.Lower than gypsum based article intensity height, water-intake rate, and various class can be installed, and can the brushing protective layer, as ceramic glaze paint etc.

Example 3, make imitation sculpture with present method; stone carving, stone inscription are time-consuming; the cost height; can be after moulding in the mould with present method; the outside is coated with and adds protective layer such as ceramic glaze paint; silicoorganic compound, teflon coating etc. have with the artistic effect the same with white marble sculpture, and with low cost.

Example 4, manufacturing activities room, prefabricated house does not have fiber reinforced material at present, after easy to crack, distortion for a long time.Can make the high indeformable firm prefabricated house of intensity with present method.

, except that the product of above introduction, can also produce with method of the present invention as products such as bathtub, sanitary ware, tubing, deck panels, non-bearing wallboard, sash.

The present invention compared with prior art produces multiple product with cheap material and simple production equipment technology, manufacture method in various moulds, have that cost is low, indeformable, glossiness is good, the mechanical index advantages of higher.

Claims

1, the main raw material prescription of the manufacture method of fabric enhanced magnesite products, it is characterized in that: magnesium chloride solution (Baume concentration 28～34 degree), aglite such as wood sawdust, the weight ratio of fiber reinforced material such as glass fibre: 0.5-8: 10-13: 0.8-1.2: 0.3-1 and an amount of other auxiliary materials such as fire retardant, water-resisting agent, defoamer etc.

2, the technology of the manufacture method of fabric enhanced magnesite products is characterized in that: through selecting materials, batching stirs, and goes into mould, and vibration is solidified, the demoulding, and maintenance is coated with and adds protective layer.

3, by claim 1 and claim 2, can in different moulds, produce multiple product, as products such as well lid, cage, prefabricated wall cabinet, imitation sculpture, firm prefabricated house, bathtub, sanitary ware, tubing, roof boarding, non-bearing wallboard, sash.
